How important are these to know for Pysch, both unit 3 and 4?And can anyone write an operational hypothesis for each of these research questions, thanks

1. Does the offer of an incentive result in greater motivation to succeed?2. Is driving ability affected by the amount of sleep deprivaion an induvidual has?3. What is the effect of rote learning information on a person's ability to recall that information when there is a need to do so?4. Is our ability to play well in a sports match impaired if we are too nervous?5. Does being permitted to eat and drink during an exam improve performance on that exam?

Sorry for the long list of questions, but I really need to get an idea of how to write one of these,

An operational hypothesis is just like a regular hypothesis in that it is a prediction. The only difference is that in an operational hypothesis, you need to tell the reader how you are going to measure whether or not the hypothesis is supported or rejected.

So, Does being permitted to eat and drink during an exam improve performance on that examOperationalised: 20 VCE Psychology students who drink 200mls of water and eat an apple during their Psychology exam will get a higher percentage of correct answers on their exam than 20 VCE Psychology students who are not to take any food or water.
